Uso de anti-hipertensivos e antidiabéticos por idosos: inquérito em Belo Horizonte, Minas Gerais, Brasil

Awareness of the diagnosis, treatment, and control of diabetes mellitus in Brazil

OBJECTIVE

To estimate the proportions of awareness, treatment, and control of diabetes mellitus (DM) in the Brazilian adult population.

METHOD

This is a cross-sectional study, with data from a representative sample of the Brazilian population, taken from the National Health Survey(PNS 2014/2015). Outcomes were defined based on glycated hemoglobin (HbA1c) measurements, self-reported DM diagnosis, and use of hypoglycemic agents or insulin. The proportion of DM awareness, treatment, and control was estimated according to sociodemographic characteristics, health conditions, and access to health services, and their respective 95% confidence intervals.

RESULTS

DM prevalence in the Brazilian population was of 8.6% (95%CI: 7.8-9.3): 68.2% (95%CI: 63.9-72.3) were aware of their diagnosis, 92.2% (95%CI: 88.6-94.7) of those who were aware were undergoing drug treatments, and, of these, 35.8% (95%CI: 30.5-41.6) had controlled HbA1c levels. The proportions of DM awareness, control, and treatment were lower in men aged 18 to 39 years, individuals with low education, without health insurance, and beneficiaries of the Bolsa Família program.

CONCLUSION

Approximately one in ten Brazilians has DM. A little more than half of this population is aware of their diagnosis, a condition measured by HbA1c dosage and clinical diagnosis. Among those who know, the vast majority are undergoing drug treatments. However, less than half of these have their HbA1c levels controlled. Worse scenarios were found in subgroups with high social vulnerability.

Avaliação dos usuários sobre as farmácias públicas no Brasil

Resumo O objetivo deste artigo é avaliar aspectos relacionados aos serviços prestados nas farmácias do SUS do Brasil, segundo a percepção dos usuários. Utilizou-se dados da Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos, realizada entre 2013 e 2014. Analisou-se indivíduos que obtiveram algum medicamento nas farmácias públicas. Para o cálculo das estimativas de prevalências, foi usado como denominador o total de usuários de medicamentos com IC95%. A partir da faixa etária de 20 a 24 anos até 60 a 64 anos observa-se diferenças significativas entre homens e mulheres, em relação ao uso de farmácias públicas. Mais de 30% das pessoas de todas as classes socioeconômica que não obtiveram medicamentos nas farmácias do SUS, nunca pensaram nessa possibilidade. Não costumam esperar para obtenção dos medicamentos e avaliação positiva do horário de funcionamento tiveram uma associação mais forte em relação a avaliação positiva dos usuários das farmácias do SUS. O horário de funcionamento e o tempo de espera são potenciais barreiras nas farmácias do SUS. A avaliação dos usuários que utilizam o SUS é positiva, mas aponta diferenças regionais e a identificação da magnitude dessas pode contribuir na formulação de políticas mais eficazes e equânimes.

Factors associated with not adopting healthy behavior among hypertensive individuals: a population-based study in Brazil

Adoption of a healthy lifestyle is strongly recommended for the control of hypertension, but professional advice alone does not ensure uptake of healthy behavior. Therefore, this study aimed to investigate the factors-associated with non-adoption of healthy behaviors among individuals with a medical diagnosis of hypertension. It was a cross-sectional study using data from the National Health Survey (PNS) carried out in Brazil in 2013, based on interviews with adults (≥18 years) (n = 60,202). The outcome variable was the non-adoption-two or fewer-of healthy behaviors (regular physical activity, recommended consumption of fruit and vegetables, no excessive alcohol consumption, no smoking, and very low/low salt intake [self-perceived]). A logistic regression model was used to verify the factors-associated with non-adoption of healthy behaviors. Approximately 64% of the study sample did not adopt healthy behaviors, i.e., they adopted two or fewer healthy habits. The most frequently mentioned healthy behaviors were not drinking excessively (91.5%), followed by not smoking (86%). Short time since disease diagnosis (OR = 1.20, 95% CI: 1.01-1.43), not using antihypertensive medication (OR = 1.38, 95% CI: 1.13-1.68), not making regular doctor visits (OR = 1.43, 95% CI: 1.23-1.65), and good self-rated health (OR = 1.16, 95% CI: 1.01-1.36) increased the chance of individuals not adopting healthy behaviors compared with their respective reference categories, independently of gender, age, schooling, and economic status. Counseling strategies should consider patient particularities, and health professionals need to be aware of issues that can interfere with the adoption of healthy behaviors of hypertensive patients.

[Polypharmacy and associated factors in elderly diabetic]

OBJECTIVES

The objective of this study was to evaluate factors related to polypharmacy and the use of potentially inappropriate medications (PIM) in elderly patients with diabetes.

METHODS

We studied 127 elderly diagnosed with type 2 diabetes, 41 males (age = 69.9 ± 6.9 years) and 86 women (age = 71.1 ± 7.7 years). For evaluation of health conditions, medication use, polypharmacy and associated factors, we used the questionnaire adapted from Morais. The drugs were classified according to the Anatomical Therapeutic-Chemical Classification System, and for identification of MPI, we adopted the criteria of Beers-Fick and PRISCUS. For data analysis, we used descriptive statistics and chi-square and Fisher Exact tests.

RESULTS

In this population, 100% of elderly using drugs. The average consumption was 5.8 per individual drug, varying from two to 14, and the prevalence of polypharmacy was 85%. Among the factors studied, only the retirement showed a statistically significant association (p <0.05) with polypharmacy. The most prevalent diseases were hypertension (92.8%), heart problems (70.8%), circulatory (40.8%) and musculoskeletal problems (44.5%). Of drugs used by the elderly, 12 of them were considered potentially inappropriate and 47.2% of the study subjects make use of these medicines regularly.

CONCLUSIONS

Thus, this study urges new thinking pharmaceutical assistance, as a practical view in full perspective and not meant only as purchasing and dispensing drugs.

Prevalência simultânea de hipertensão e diabetes em idosos brasileiros: desigualdades individuais e contextuais

Resumo A prevalência da simultaneidade de doenças específicas nos idosos ainda é pouco descrita na literatura. O objetivo do estudo foi estimar a prevalência simultânea de hipertensão arterial e diabetes mellitus em idosos brasileiros, e os fatores contextuais e individuais a ela associados. Estudo transversal de base populacional com idosos (≥ 60 anos) entrevistados pelo Vigitel em 2012 (n = 10.991). As análises foram realizadas por meio de regressão de Poisson multinível no Stata 12. A média de idade dos idosos foi de 69,4 anos e a prevalência simultânea das doenças foi de 16,2% com variação nas capitais brasileiras. Em São Paulo e Curitiba as prevalências foram mais elevadas do que em Boa Vista e Manaus. Maiores prevalências foram observadas nas capitais das regiões Sul/Sudeste/Centro-Oeste, nos idosos de cor preta e parda, naqueles com escolaridade ≤ 8 anos de estudo, nos não fumantes e ex-fumantes, e com excesso de peso. Verificou-se o efeito da região geográfica na prevalência simultânea pela elevação de 23,5% na magnitude da razão de prevalencia, após ajuste para todas as variáveis individuais. Por meio do estudo, foi possível dimensionar o efeito do contexto onde estão inseridos os idosos (região de residência) sobre a prevalência das principais doenças que acometem e relacionam-se à mortalidade na população idosa na atualidade.

[Prevalence of arterial hypertension, diabetes mellitus, and adherence to behavioral measures in the city of São Paulo, Brazil, 2003-2015]

The objective was to compare the estimates for prevalence of diabetes, hypertension, and behavioral measures to control these diseases. Data were analyzed for the adult population from Health Surveys in the city of São Paulo, Brazil, in 2003, 2008, and 2015. Prevalence rates and 95% confidence intervals (95%CI) were calculated for the following: hypertension, diabetes, and practices to control these diseases (diet, physical activity, oral medication, insulin, nothing). Estimates were compared by age and sex-adjusted Poisson regression and analyzed according to the 20-59-years and 60-and-older age brackets. The data were presented comparing 2008 to 2003 and 2015 to 2003. Among persons 20 to 59 years of age, there was an increase in the prevalence rates for: hypertension in 2003-2015 (PR = 1.27; 95%CI: 1.03-1.60) and diet for both periods (2003-2008, PR = 2.04; 95%CI: 1.42-2.91; and 2003-2015, PR = 1.51; 95%CI: 1.05-2.15). Among persons 60 years and older: diabetes (PR = 1.29; 95%CI: 1.08-1.56) and oral medication to control diabetes (PR = 1.38; 95%CI: 1.17-1.63), both in 2003-2015; hypertension in 2003-2015 (PR = 1.19; 95%CI:1.05-1.39); and diet and oral medication to control hypertension in 2003-2008 (PR = 1.20; 95%CI: 0.95-1.51 and PR = 1.02; 95%CI: 0.95-1.09, respectively). The results are important for surveillance and monitoring of the target indicators and provide backing for planning health care activities in the city of São Paulo. Linking and aligning effective and integrated interventions is indispensable for reducing and controlling these chronic noncommunicable diseases.

Cytotoxic and genotoxic effects of antihypertensives distributed in Brazil by social programs: Are they safe?

Hypertension, a chronic non-transmissible multifactorial condition, it is highly frequent in Brazil, affecting about 32.5% of the population over 25 years of age. It is characterized by the sustained increase in systolic and diastolic blood pressure levels above 140 mmHg and 90 mmHg, respectively. It is the major aggravating factor in cardiovascular complications and the appearance of other comorbidities. Aiming to promote greater adherence to treatment and improve the population's access to basic medicament, in 2004 the Federal Government created the Programa Farmácia Popular do Brasil (PFPB); partnership with private institutions that provides the population with medicament to control hypertension, free of charge or subsidized at up to 90% of the value. The PFPB distributes the anti-hypertensives atenolol, captopril, enalapril, hydrochlorothiazide, losartan and propranolol. In this way, this work aims to evaluate the genotoxic potential of antihypertensives in human lymphocytes and macrophages, since they are widely used drugs and with few studies about their genotoxicological safety. The tests were developed from cell cultures treated with five different antihypertensive concentrations, all based on plasma peaks, evaluating cell viability, DNA damage index and DNA double strand breakdown. The results show that, as the concentration of captopril and enalapril maleate increased, cell viability decreased. In addition, a DNA damage was observed with the use Captopril and Enalapril in the higher concentrations. Hydrochlorothiazide also caused DNA damage in the five doses tested. Regarding the breaking of double strands of DNA, all the compounds showed increased ruptures. This decrease in dsDNA is dose dependent for all compounds tested. The set of results shows that the use although frequent still requires care and greater knowledge. In general, the antihypertensive drugs that proved to be safer in relation to the genetic damage tested were Losartan and Propranolol.

Medication use by the elderly: analysis of prescribing, dispensing, and use in a medium-sized city in the state of São Paulo

Abstract Objective: To describe the prescribing, dispensing, use, adhesion, and storage of medicines to and by the elderly. Method: A descriptive cross-sectional study was performed in Estratégia Saúde da Família (Family Health Strategy) health centers (ESF), in Marília in the state of São Paulo, Brazil, based on the records of and interviews with 114 individuals seven to ten days after a medical consultation. A descriptive analysis was carried out. Results: The mean number of prescribed drugs was 4.98 per elderly patient. Of the total number of prescribed drugs, 81.5% were supplied by public services, with the nutrient (50%); antilipemic (62.1%); analgesic (30.7%); dermo-protector (66.6%); herbal (40%) and parasite and antifungal (37.5%) classes dispensed the least. A total of 83.8% of the prescribed drugs were used, while the drugs dispensed at the lowest rates were not used by the elderly, except for analgesics. A total of 40.3% of the respondents exhibited low adherence. Most stored their medicines in a suitable place. Conclusion: The prescribing, dispensing, use and storage of medications to and by the elderly can be considered effective, but adherence remains low, requiring new strategies and interventions.

Sources for obtaining drugs for hypertension in Brazil: results from the National Health Survey, 2013

OBJECTIVE

To analyze the sociodemographic differences among adults with hypertension regarding the sources for obtaining drugs for hypertension treatment in Brazil.

METHODS

This is a secondary analysis of data from the National Health Survey 2013; the outcomes considered for the analysis were the sources for obtaining drugs for treating high blood pressure.

RESULTS

The great majority (74%) of patients with hypertension taking drugs use a single source for obtaining them, 7.3% (95%CI 6.4 - 8.4) reported getting all the drugs through private health plans, 22.7% (95%CI 21.0 - 24.4) by pharmacies of the public health system, 21.8% (95%CI 20.2 - 23.4) by the Popular Pharmacy Program, and about one-third (29.5%; 95%CI 27.7 - 31.4) exclusively by commercial pharmacies. Having the public health system as the single source for obtaining the drugs was found to decrease with age, was lower in white people, decreased strongly with increase in education, and was lower for residents in the North region. Exclusive obtainment through the Popular Pharmacy Program was lower for people with higher education. Obtainment in commercial pharmacies was positively associated with being male, with higher education level, being older, and having white skin color. Obtainment using more than one source was positively associated with increasing age and inversely associated with higher education levels.

CONCLUSIONS

The results allowed the identification of a trajectory of patients in obtaining drugs for the treatment of hypertension, aiming at explaining how the drugs are obtained and the impact of public policies in this sector in the country.

Factors associated with polypharmacy among elderly people receiving care under the family health strategy

Abstract Objective: to identify the medication profile, the prevalence of polypharmacy and associated factors among elderly people receiving care from Family Health Strategy teams. Method: an analytical, document-based, cross-sectional survey with a quantitative approach was conducted in Brazlândia in the Distrito Federal, Brazil, with a sample of 211 elderly people enrolled in and receiving care from one of the local Family Health Strategy teams. Data were submitted to bivariate analysis and multiple analysis through logistic regression. Results: a considerable number of the elderly (62, 29.4%) were undergoing polypharmacy. The majority (56, 26.5%) used three different classes of drug, with antihypertensive drugs the most used. Diabetes mellitus, cardiovascular complications and the use of antihypertensive drugs were factors associated with polypharmacy. Conclusion: polypharmacy is a worrying reality and demands a new approach on the part of professionals, as this important aspect of geriatrics should be carefully evaluated to avoid harm and iatrogeny among the elderly.

Factors associated with the use of antihypertensives among seniors

OBJECTIVE

Analyze the use of antihypertensives among seniors and the association with socioeconomic and behavioral characteristics.

METHODS

In this seriate cross-sectional study, we used data from the Saúde, Bem Estar e Envelhecimento study (SABE – Health, Well-being, and Aging), conducted in 2000, 2006, and 2010 in the city of São Paulo. Association between the use of antihypertensives and the demographic, behavioral, and socioeconomic characteristics and risk factors was analyzed by using multilevel logistic regression models.

RESULTS

We observed increased proportion of use of antihypertensive, from 48.7% in 2000 to 61.3% in 2006, reaching 65.7% in 2010. Among the seniors who made use of this type of medicine, we also observed increased adoption of combined therapy in the period, from 69.9% to 82.6% from 2000 to 2006 and reaching 91.6% in 2010. Multilevel analysis indicated statistically significant increase in use of antihypertensives, even after control by socioeconomic and behavioral characteristics, both in 2006 and in 2010 (OR = 1.90; 95%CI 1.60–2.24 and OR = 1.94; 95%CI 1.62–2.33, respectively). Use of antihypertensives showed positive association with females, higher age group, black skin color, overweight, and smoking history.

CONCLUSIONS

High use of antihypertensives and its association with sociodemographic and behavioral characteristics can help guide the discussion of strategies to improve the epidemiological situation, the quality of life, and the distribution of medicines to the elderly population.

Uso contínuo de medicamentos e condições de trabalho entre motoristas de caminhão

Resumo Os motoristas de caminhão têm sido pouco explorados quanto aos problemas de saúde que os acometem e, principalmente, quanto ao seu perfil de consumo de medicamentos. Este estudo teve o objetivo de determinar o uso contínuo de medicamentos, por motoristas de caminhão, e identificar as características profissionais associadas. Para a sua realização, conduziu-se um estudo transversal com motoristas de caminhão estacionados no Pátio de Triagem do Porto de Paranaguá, Paraná, Brasil. Realizou-se uma entrevista com obtenção de dados socioeconômicos, problemas de saúde, condições de trabalho e uso contínuo de medicamentos. Dos motoristas avaliados (n = 665), 21,1% referiram utilizar algum medicamento continuamente, com destaque para o captopril (10,7%), metformina (10,3%), omeprazol (6,2%) e sinvastatina (6,2%). Motoristas com dezesseis anos ou mais de experiência profissional (RP 1,67; IC 95% 1,11-2,51), proprietários do próprio caminhão (RP 1,38; IC 95% 1,03-1,86) e que não possuíam vínculo empregatício formal (RP 1,49; IC 95% 1,11-2,00) apresentaram maior prevalência de uso contínuo de medicamentos. Observa-se que algumas condições de trabalho têm importante papel do uso contínuo de medicamentos pelos motoristas de caminhão.

Access to and use of high blood pressure medications in Brazil

OBJECTIVE

To analyze the access to and use of medicines for high blood pressure among the Brazilian population according to social and demographic conditions.

METHODS

Analysis of data from Pesquisa Nacional Sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines), a nationwide cross-sectional, population-based study, with probability sampling, carried out between September 2013 and February 2014 in urban households in the five Brazilian regions. The study evaluated the access and use of medicines to treat people with high blood pressure. The independent variables were gender, age, socioeconomic status and Brazilian region. The study also described the most commonly used drugs and the percentage of people treated with one, two, three or more drugs. Point estimations and confidence intervals were calculated considering the sample weights and sample complex plan.

RESULTS

Prevalence of high blood pressure was 23.7% (95%CI 22.8-24.6). Regarding people with this condition, 93.8% (95%CI 92.8-94.8) had indication for drug therapy and, of those, 94.6% (95%CI 93.5-95.5) were using the medication at the time of interview. Full access to medicines was 97.9% (95%CI 97.3-98.4); partial access, 1.9% (95%CI 1.4-2.4); and no access, 0.2% (95%CI 0.1-0.4). The medication used to treat high blood pressure, 56.0% (95%CI 52.6-59.2) were obtained from SUS (Brazilian Unified Health System), 16.0% (95%CI 14.3-17.9) from Popular Pharmacy Program, 25.7% (95%CI 23.4-28.2) were paid for by the patients themselves and 2.3% (95%CI 1.8-2.9) were obtained from other locations. The five most commonly used drugs were, in descending order, hydrochlorothiazide, losartan, captopril, enalapril and atenolol. Of the total number of patients on treatment, 36.1% (95%CI 34.1-37.1) were using two medicines and 13.5% (95%CI 12.3-14.9) used three or more.

CONCLUSIONS

Access to medicines for the treatment of high blood pressure may be considered high and many of them are available free of charge. The most commonly used drugs are among those recommended as first-line treatment for high blood pressure control. The percentage of people using more than one drug seems to follow the behavior observed in other countries.

OBJETIVO

Analisar o acesso e a utilização de medicamentos para a hipertensão na população brasileira segundo condições sociais e demográficas. Análise dos dados da Pesquisa Nacional Sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos, estudo nacional de delineamento transversal de base populacional, com amostra probabilística, realizado entre setembro de 2013 e fevereiro de 2014 em domicílios urbanos nas cinco regiões do Brasil. Avaliou-se o uso e acesso aos medicamentos para os cuidados com pessoas que apresentam hipertensão arterial. As variáveis independentes utilizadas foram sexo, idade, nível socioeconômico e região do País. Também foram descritos os fármacos mais utilizados e a proporção de pessoas tratadas com um, dois, três ou mais fármacos. As estimativas de ponto e os intervalos de confiança foram calculados considerando os pesos amostrais e o plano complexo da amostra. A prevalência de hipertensão arterial foi de 23,7% (IC95% 22,8-24,6). Das pessoas com a condição, 93,8% (IC95% 92,8-94,8) tinham indicação de tratamento com medicamentos e, destes, 94,6% (IC95% 93,5-95,5) estavam usando os medicamentos no momento da entrevista. O acesso total aos medicamentos foi de 97,9% (IC95% 97,3-98,4); o acesso parcial, de 1,9% (IC95% 1,4-2,4); e o acesso nulo, de 0,2% (IC95% 0,1-0,4). Dos medicamentos utilizados para tratar a hipertensão, 56,0% (IC95% 52,6-59,2) foram obtidos no SUS, 16,0% (IC95% 14,3-17,9), no Programa Farmácia Popular, 25,7% (IC95% 23,4-28,2) pago do próprio bolso e 2,3% (IC95% 1,8-2,9) em outros locais. Os cinco fármacos mais utilizados foram, em ordem descrente, hidroclorotiazida, losartana, captopril, enalapril e atenolol. Do total de tratados, 36,1% (IC95% 34,1-37,1) estavam usando dois fármacos e 13,5% (IC95% 12,3-14,9) utilizavam três ou mais fármacos.

CONCLUSÕES

: O acesso aos medicamentos para tratamento da hipertensão pode ser considerado elevado e grande parte desses medicamentos é obtida gratuitamente. Os fármacos mais utilizados estão entre os preconizados como de primeira linha para o controle de hipertensão arterial. A proporção de pessoas utilizando mais de um fármaco parece seguir o comportamento observado em outros países.

Free access to medicines for the treatment of chronic diseases in Brazil

OBJECTIVE

To analyze the free access to medicines for the treatment of chronic diseases in the Brazilian population, according to demographic and socioeconomic factors. We also analyzed the most used pharmacological groups, according to funding source: free-of-charge or out-of-pocket paid.

METHODS

Analysis of data from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines), a population-based household survey, of cross-sectional design, based on probabilistic sample of the Brazilian population. We analyzed as outcome the prevalence of free access (free-of-charge) to all medicines for treatment of the reported chronic diseases, in the last 30 days. We studied the following independent variables: sex, age group, education in complete years of school, economic class, health plan, and geographical region of residence. We estimated the prevalences and 95% confidence intervals (95%CI) and applied the Pearson's Chi-squared test to assess the differences between the groups, considering a 5% significance level.

RESULTS

About half of adults and older adults who have had full access to the treatment of chronic diseases in Brazil obtained all needed medicines for free (47.5%; 95%CI 45.1-50.0). The prevalences of free access were higher among men (51.4%; 95%CI 48.1-54.8), age group of 40-59 years (51.1%; 95%CI 48.1-54.2), and in the poorest social classes (53.9%; 95%CI 50.2-57.7). The majority of medicines that act on the cardiovascular system, such as diuretics (C03) (78.0%; 95%CI 75.2-80.5), beta-blockers (C07) (62.7%; 95%CI 59.4-65.8), and the agents that work in the renin-angiotensin system (C09) (73.4%; 95%CI 70.8-75.8), were obtained for free. Medicines that act on the respiratory system, such as agents against obstructive airway diseases (R03) (60.0%; 95%CI 52.7-66.9) were mostly paid with own resources.

CONCLUSIONS

Free access to medicines for treatment of chronic diseases occurs to a considerable portion of the Brazilian population, especially for the poorest ones, indicating decreased socioeconomic inequalities, but with differences between regions and between some classes of medicines.

OBJETIVO

Analisar o acesso gratuito ao tratamento medicamentoso para doenças crônicas na população brasileira, segundo fatores socioeconômicos e demográficos. Analisaram-se também os grupos farmacológicos mais utilizados, segundo fonte de financiamento: gratuito ou pago do próprio bolso.

MÉTODOS

Análise de dados oriundos da Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM), inquérito domiciliar de base populacional, de delineamento transversal, baseado em amostra probabilística da população brasileira. O desfecho analisado foi a prevalência de acesso gratuito (sem pagamento) a todos os medicamentos para tratamento das doenças crônicas referidas, nos últimos 30 dias. As variáveis independentes investigadas foram: sexo, faixa etária, escolaridade em anos completos de estudo, classe econômica, plano de saúde e região geográfica de residência. Foram estimadas as prevalências e calculados intervalos de 95% de confiança (IC95%) e aplicado o teste Qui-quadrado de Pearson para avaliação das diferenças entre os grupos, considerando nível de significância de 5%.

RESULTADOS

Cerca de metade dos adultos e idosos que tiveram acesso total ao tratamento de doenças crônicas no Brasil obtiveram todos os medicamentos que necessitavam gratuitamente (47,5%; IC95% 45,1-50,0). As prevalências de acesso gratuito foram maiores entre os homens (51,4%; IC95% 48,1-54,8), na faixa etária de 40-59 anos (51,1%; IC95% 48,1-54,2) e nas classes sociais mais pobres (53,9%; IC95% 50,2-57,7). Grande parte dos medicamentos que atuam no sistema cardiovascular, como os diuréticos (C03) (78,0%; IC95% 75,2-80,5), betabloqueadores (C07) (62,7%; IC95% 59,4-65,8) e os agentes que atuam no sistema renina-angiotensina (C09) (73,4%; IC95% 70,8-75,8) foram obtidos de forma gratuita. Os medicamentos que atuam no sistema respiratório como os agentes contra doenças obstrutivas das vias aéreas (R03) (60,0%; IC95% 52,7-66,9) foram na sua maioria pagos do próprio bolso.

CONCLUSÕES

O acesso gratuito aos medicamentos para tratamento das doenças crônicas ocorre para uma considerável parcela da população brasileira, principalmente para os mais pobres, indicando diminuição das desigualdades socioeconômicas, mas com diferenças regionais e entre algumas classes de medicamentos.

[Sources of medicines for hypertension and diabetes in Brazil: telephone survey results from Brazilian state capitals and the Federal District, 2011]

This study aimed to analyze differences between patients with diabetes and hypertension in drug treatment and their sources for obtaining medication. This was a cross-sectional study with data from the VIGITEL telephone survey in 2011 in Brazil's state capitals and Federal District. Some 72% of the 15,027 hypertensive patients and 78.2% of the 4,083 diabetics were on medication; 45.8% of the hypertensive patients obtained their medications from public health units, 15.9% from the Popular Pharmacy program, and 38.3% from drugstores, pharmacies, and other sources. The rates among diabetics were 54.4%, 16.2%, and 29.4%, respectively. In the public health units the percentages were highest among individuals with less schooling, black or brown skin, and without private health plans, while the percentages in the Popular Pharmacy program and drugstores/pharmacies and other sources were higher among individuals with more schooling, white skin, and private health plans. Access to different sources of medicines showed disparities between Brazil's regions and state capitals and between social segments of the population.

Clinical and epidemiological profile of elderly patients with Chagas disease followed between 2005-2013 by pharmaceutical care service in Ceará State, Northeastern Brazil

By controlling the transmission of Chagas disease, the challenge of providing assistance to millions of infected patients that reach old age arises. In this study, the socioeconomic, demographic and comorbidity records of all elderly chagasic patients followed at the Pharmaceutical Care Service of the Chagas Disease Research Laboratory were assessed. The information related to the clinical form of the disease was obtained from medical records provided by the Walter Cantídio University Hospital. The profile of the studied population was: women (50.5%); mean age of 67 years; retired (54.6%); married (51.6 %); high illiteracy rate (40.2%); and family income equal to the minimum wage (51.5%). The predominant clinical forms of Chagas disease were cardiac (65.3%) and indeterminate (14.7%). The main electrocardiographic changes were the right bundle branch block (41.0%), associated or not with the anterosuperior left bundle branch block (27.4%). The average number of comorbidities per patient was 2.23 ± 1.54, with systemic arterial hypertension being the main one found (67.0%). It was found that the elderly comprise a vulnerable group of patients that associate aging with cardiac and/or digestive disorders resulting from the evolution of Chagas disease and other comorbidities, which requires special attention from health services to ensure more appropriate medical and social care.

Self-reported diabetes in older people: comparison of prevalences and control measures

OBJECTIVE

The objective of this study was to analyze the prevalence of diabetes in older people and the adopted control measures.

METHODS

Data regarding older diabetic individuals who participated in the Health Surveys conducted in the Municipality of Sao Paulo, SP, ISA-Capital, in 2003 and 2008, which were cross-sectional studies, were analyzed. Prevalences and confidence intervals were compared between 2003 and 2008, according to sociodemographic variables. The combination of the databases was performed when the confidence intervals overlapped. The Chi-square (level of significance of 5%) and the Pearson's Chi-square (Rao-Scott) tests were performed. The variables without overlap between the confidence intervals were not tested.

RESULTS

The age of the older adults was 60-69 years. The majority were women, Caucasian, with an income of between > 0.5 and 2.5 times the minimum salary and low levels of schooling. The prevalence of diabetes was 17.6% (95%CI 14.9;20.6) in 2003 and 20.1% (95%CI 17.3;23.1) in 2008, which indicates a growth over this period (p at the limit of significance). The most prevalent measure adopted by the older adults to control diabetes was hypoglycemic agents, followed by diet. Physical activity was not frequent, despite the significant differences observed between 2003 and 2008 results. The use of public health services to control diabetes was significantly higher in older individuals with lower income and lower levels of education.

CONCLUSIONS

Diabetes is a complex and challenging disease for patients and the health systems. Measures that encourage health promotion practices are necessary because they presented a smaller proportion than the use of hypoglycemic agents. Public health policies should be implemented, and aimed mainly at older individuals with low income and schooling levels. These changes are essential to improve the health condition of older diabetic patients.

Hipertensão arterial referida e utilização de medicamentos de uso contínuo no Brasil: um estudo de base populacional

O objetivo do presente estudo foi estimar a prevalência e fatores associados à não utilização de algum medicamento de uso contínuo nos indivíduos de 30-79 anos que referiram hipertensão arterial na Pesquisa Nacional por Amostra de Domicílios (PNAD-2008), Brasil. Razões de prevalência (RP) e respectivos intervalos de 95% de confiança (IC95%) foram obtidos por meio de regressão de Poisson. A proporção de indivíduos que não utilizava medicamentos de uso contínuo foi de 17%. Características positivamente associadas à não utilização foram: sexo masculino, residência nas regiões Norte, Nordeste, Centro-oeste e hábito de fumar. O não uso desses medicamentos diminuiu com a idade, renda domiciliar per capita, número de doenças crônicas e de consulta médica nos últimos 12 meses; foi menor entre os que tinham 11 anos e mais de estudo (RP = 0,92; IC95%: 0,86-0,98), nos que não trabalhavam nem estavam desempregados e nos que não realizavam atividade física. A adesão à terapia medicamentosa no controle de hipertensão arterial é necessária e requer investimento na atenção primária, na melhoria no acesso aos serviços de saúde e no enfretamento das desigualdades regionais, sociais e de gênero.

Prevalência de hipertensão arterial sistêmica em idosos no Brasil entre 2006 e 2010

Objetivo: observar a evolução da prevalência de hipertensão arterial sistêmica (HAS) em idosos entre 2006 e 2010 no Brasil. Métodos: estudo descritivo, ecológico, quantitativo, de um período entre 2006 e 2010, com dados coletados do Departamento de Informática do Sistema Único de Saúde (DATASUS) relacionados ao sexo, região e escolaridade na faixa etária de 65 anos ou mais.  Resultados: na análise entre regiões brasileiras, não houve diferença significativa nos anos analisados. Na comparação entre os sexos, a prevalência de HAS acima de 65 anos nas mulheres foi maior que nos homens. Com relação ao nível de escolaridade, foi encontrado que a prevalência no ano de 2006 foi significativamente menor do que nos anos de 2008 e 2009 entre pessoas com 9 a 11 anos de educação formal. Entre as regiões, quanto menor o nível de escolaridade, maior a prevalência de hipertensão. Conclusão: a prevalência da HAS acima dos 65 anos não seguiu uma tendência linear, mas manteve-se elevada, com predomínio em idosos do sexo feminino e em idosos com baixa escolaridade, chamando a atenção para a necessidade de ações de prevenção dos fatores de risco e acompanhamento em longo prazo dos idosos hipertensos.
